Performance in corrosion control programs should be measured — not assumed. Municipal utilities across the United States rely on documented data when evaluating strategies to reduce metal release and support compliance with the EPA’s Lead and Copper Rule (LCR). As infrastructure modernization continues nationwide, treatment optimization remains an important component of comprehensive water quality management. …

Permanganate is widely used across municipal and industrial water treatment applications due to its strong oxidizing capabilities and proven performance in processes such as taste and odor control, iron and manganese removal, and remediation. At Carus, we offer CAIROX® potassium permanganate and CARUSOL® sodium permanganate for water treatment and RemOx® S ISCO reagent and RemOx® …

Ethylene oxide (EtO) plays a critical role in modern manufacturing, particularly in medical device sterilization, pharmaceutical production, and specialty chemical processes. Its effectiveness as a sterilant and chemical intermediate makes it difficult to replace in many applications. However, EtO is also a hazardous air pollutant, and increasing awareness of its health risks has intensified scrutiny …

Consider How It May Impact Your Corrosion Control Program Many water treatment facilities are currently evaluating changes to how they treat drinking water. These changes can be driven by a number of factors, including capital improvements, plant expansions, regulatory updates, or the addition of new treatment technologies, including systems designed to address PFAS. While PFAS …

When remediation teams encounter chlorinated solvent contamination in low-permeability soils like clay, standard approaches can quickly run into challenges. Traditional dig-and-haul strategies can become costly, especially when disposal fees and trucking add up. At a former maintenance facility in the Midwest, our remediation partner faced just that — high concentrations of trichloroethene (TCE) in cohesive …

When you’re dealing with a contaminated site that just won’t play by the rules, standard remediation approaches can fall short. Whether you’re facing multiple contaminants, tricky geologies, or long remediation timelines, going all-in on a single technology might not deliver the results you need. That’s where hybrid remediation strategies come into play—particularly the powerful combination …

When you’re tasked with mitigating air pollutants like ozone, carbon monoxide, VOCs, or ethylene oxide, choosing the right catalyst isn’t just a technical decision—it’s a regulatory, operational, and financial one. That’s where Carus’ CARULITE® catalyst solutions come in. With options tailored to specific pollutants, operating conditions, and substrate configurations, CARULITE products help streamline emissions control …

For more than 100 years, Carus has been at the forefront of permanganate innovation—delivering the trusted oxidizing power on which industries depend. Today, CAIROX® potassium permanganate remains the benchmark for quality, safety, and performance in industrial oxidation. Backed by a century of experience and certified to rigorous standards, CAIROX continues to drive reliable results for …

Overview Selecting the right oxidant can have a major impact on treatment efficiency, operational safety, and overall cost. For environmental engineers, utility managers, and operators, understanding the key differences between potassium and sodium permanganate is essential. This guide demystifies the choice between these two powerful oxidants—helping you make the best decision for your unique process. …

Helping Mining Operations Achieve Compliance, Sustainability, and ESG Goals Overview Mining operations face complex water treatment challenges. Wastewater streams often contain dissolved metals (iron, manganese, etc.), cyanide, acidity, and suspended solids — each with its own regulatory and environmental risks. As global discharge limits tighten, site managers and compliance officers are seeking reliable, field-proven solutions …
